Editor:- March 9, 2016 - Micron was ranked #5 in the new Q4 2015 edition of the Top SSD Companies List which is researched and published by

Micron first entered this series of SSD reader search ranked companies in Q1 2010 and its highest rank (so far) was #3 in Q3 2015.

In the context of the DRAM market - a blog of DRAM brands by revenuefrom DRAMeXchange which was reported in SSD news in February 2016 said that Micron was the 3rd largest supplier of DRAM in Q4 2015.

Micron is one of 10 significant companies which have made product announcements related to the SCM DIMM wars market.

Readers who are stakeholders in the SSD and memory markets often ask me to interpret SSD related news and market trends in the context of specific companies (including their own). In a Micron context here are some articles you may find strategically interesting:-

Micron? - from the enterprise SSD perspective

Editor:- June 10, 2015 - here's a summary of how I view Micron from the enterprise SSD perspective. It's based on some conversations with readers in May and early June 2015 re what I thought about Micron's Storage Unit.

In the past few quarters - from my perspective and past conversations with Micron re enterprise SSD - I rated Micron as having a very weak direct understanding of the enterprise SSD systems market and no real strong products apart from standard offerings which are easily substitutable.

From the short term business perspective that weakness makes it less risky for other SSD companies (without fabs) to do business with Micron – because they can judge Micron is not well placed to replace them.

Micron is the only company (among the major memory and HDD companies in the same market) which hasn't acquired any significant enterprise SSD companies in the past 12 to 18 months. For years they didn't understand the enterprise and they still don't have the IP or brands needed. So they should feel strong pressure to do something. But making a big move after years of doing nothing is risky too.

Taken together Micron's enterprise storage strategy has not met the basic needs of Micron as a memory company. It doesn't have any strong SSD architectures and systems roadmaps of its own.

Who's who in SSD? - Micron - by Zsolt Kerekes, editor - - February 2014

In the quarter ended November 28, 2013 - Micron said that about 50% of its nand flash memory bits went into SSDs.

Micron also reported significant growth in its server RAM business in this quarter.

However, in the next few years I think it's likely that this server DRAM business will be impacted by the growing adoption of server based flash - initially by PCIe SSDs (a market in which Micron itself participates directly) and later to a growing extent by memory channel flash SSDs in the form represented by flash DIMMs from competitor SanDisk.

The general effect of server based flash on server DRAM is to reduce the number of servers required to service like for like apps and users. (SSD-CPU equivalence)

In the past few years, however, the RAM impact of this transition has mostly been to move more RAM into fewer servers.

In the next few years, however, flash SSDs may also begin to replace a proportion of memory capacity which was previously done by DRAM.

Micron doesn't currently have a low latency, high capacity, flash DIMM SSD technology platform in its product line. (Micron's hybrid DIMMs - which are flash backed DRAM DIMMs are entirely different.)

But I think it's inevitable that Micron will - at some stage in 2014 or 2015 - have to publicly address this flash DIMM SSD accelerator product gap / opportunity / threat to maintain confidence in its server customer base.

Possible ways of doing this are:-
  • ammending the Hybrid Memory Cube architecture to support internal flash controllers (a possibility I wrote about back in 2011)
  • licensing or acquiring a similar flash DIMM interface controller technology.
  • developing something similar internally
  • launching patent lawsuits to slow down competitors
Clearing the patent and IP decks in readiness for the above options for that may have been one of the factors in the December 2013 patent deal with Rambus.

In a related conference call - Satish Rishi, CFO - Rambus said "we haven't licensed the entire controller space... besides DRAM, and on that side of the industry, we're looking to have more licensees... ...Today most of our patents do not read on the interfaces for non-volatile memory... But over time, I think that's going to change and we expect that some of the novel technologies in the non-volatile space as the speeds get higher will probably adopt the type of interfaces that the DRAM industry has used. So we have a lot of upside potential." ( transcript)

My guess is that - Micron will be conflicted about investing too much, too soon in memory channel SSDs for the same reasons that hard drive vendors originally ignored SSDs.

In the present state of the SSD market - Micron may regard the short term market opportunity of memory channel SSD as - being small compared to something they already do (PCIe SSDs) and - in the long term - as damaging to their DRAM revenue if it succeeeds.

re Micron and SSDs - by Zsolt Kerekes, editor - January 2013

Overriding all previous faltering (and sometimes misdirected) steps taken by Micron in the SSD market in recent years - the company's 2 biggest legacy achievements in the SSD market upto now were clearly revealed in 2012. They were:-
  • revealing that 1/3 of Micron's nand flash trade sales go into SSDs.

    From my point of view - having discussed this type of transition with many of the world's leading memory companies years ago when SSDs were under 1% of their customer sales and not even in their business radar - it's hard to state how significant this is.

    Some other ways you can look at it are...

    Current worldwide memory fab capacity can easily support 3x the SSD volume and probably 10x the annual SSD capacity using already started manufacturing processes.

    Owning SSD brands is now an essential part of forward integration for managing a successful memory business.

    Memory businesses will not be able to survive profitably without strongly estalished and tied SSD routes to market.

    That's because customers want SSDs - not memory. And because SSD makers can switch memory suppliers more easily than server and PC makers could switch them - the position of being outside the SSD box as a commodity supplier of memory isn't attractive.

Who's who in SSD? - by Zsolt Kerekes, editor - June 2012

Micron sampled its 1st SSD products in early 2008 and made its first appearance in the Top 20 SSD Companies list in Q3 2010. But the company dropped out of the list again in the most recent edition of the top SSD companies (Q1 2012).

I spoke to Ed Doller, VP of Enterprise SSD Solutions recently to discuss their enterprise SSD products.

I had been following up a chain of SSD contacts within the company - and I was looking forward to finally getting some useful information about their enterprise SSDs.

I started by saying that I was surprised that the information which is publicly available on Micron's enterprise SSD web pages - lacks the essential data that any serious designer would need to know in order to decide whether to shortlist Micron as a possible supplier.

At the time I looked (in May 2012) the PCIe SSD product datasheets - for example - didn't say anything at all about the internal architecture - and they were light on many performance details too. I wondered if I had been looking in the right places. To me Micron's enterprise SSD web pages gave me a message of product intentions rather than products which were in production and had been fully characterized.

It wasn't me. I learned that's just the way they do things.

Ed Doller said that the company doesn't supply the kind of detailed internal architecture information I was asking for unless they are talking directly to a potential customer which they have identified by their sales efforts and even in those cases the prospects (mostly in the top tier of computer oems) would need to sign an NDA first.

I said Micron's approach - witholding even the most basic technical info - showed me that Micron doesn't know how to market enterprise SSDs and that unless Micron changes the way they presented their SSD info online they would miss out on a big chunk of the enterprise market.

I said my readers include the biggest buyers and specifiers of SSDs and that with so many vendors in the enterprise SSD market - the designers tend to shortlist suppliers from what they see online - because they don't have time to talk to everyone or test more than a small number of different products.

Neither Micron nor anyone else can compile a list of who the biggest SSD users are based on traditional sales data. Because there are many companies which will be huge consumers of enterprise SSDs in the online data economy which fall outside the traditional prospects lists. These SSD users will make the first moves to choose their SSD partners - not the other way around.

I said it's a valid business decision to do business the way Micron was doing it. But to my way of thinking marketing enterprise SSDs the same way as commodity memory products - wasn't the way to maximize their business potential.

One of these days I will have to read some blogs about diplomacy. I thought we weren't getting anywhere but Ed Doller did confirm that they have designed their own SSD controller architecture for use in their enterprise SSDs. And to me - it's a safe inference is that they are also in the DSP IP in SSD pack too.

That means Micron is a more significant SSD IP company than you would think simply by looking at the null data content in their SSD web pages.

If you're thinking of designing in Micron's enterprise SSDs - I would say - don't waste too much of your time visiting Micron's web site - because you won't learn anything useful there. They don't have a scalable online process of disseminating the information you need. You'll need to talk to a real person in their SSD business - and then wait weeks or months - depending how busy they are - to talk to a product specialist who can answer the type of detailed technical questions - which real enterprise SSD companies put in their public web pages. (I'm still waiting to get my questions answered - and when I hear I'll let you know.)

But to get the balance right Micron isn't the only semiconductor company which doesn't know how to market systems products. That kind of thinking is built into the DNA of many chip makers.

These antiquated oem component oriented ways of developing business worked well in the past - but the SSD market isn't like the PC or server market. One of the interesting things about the SSD market is how the memory makers, and the traditional storage companies have very different approaches to each other and also to the pure play SSD companies. There's no right and wrong way. It's whatever gets the business to the next level. But if you're selecting an SSD supplier - then these differences in thinking and doing business and risk management can be more important than the exact specs and prices of the products.

Another positive thing about Micron - is thatall the SSD people I spoke to were very enthusiastic about the enterprise SSD market and optimistic about the advantages Micron had in the SSD business - by being part of a memory company.

They were surprised but not at all offended when I said that it was only an advantage if everything worked out right - but that the advantage of not being tied to a particular memory supplier for designers in competing SSD companies was that they could go with whichever memory product looked best at the time.

I think we'll be hearing a lot more from Micron - but other enterprise PCIe SSD makers won't be putting them at the top of their list of competitors to worry about just yet.

For competing SSD suppliers see these directories:- PCIe SSDs, 2.5" SSDs and SATA SSDs.

Micron recently acquired the assets of UK based Virtensys which marketed rackmount SSDs stuffed with Micron's PCIe SSDs with a patented multi-server sharing virtualization interface.

The leading companies in the enterprise acceleration PCIe SSD market which Micron has to compete with are:- Fusion-io, Texas Memory Systems, OCZ and Virident Systems.

And in the next level down are:- STEC and LSI and then another 40 or so other companies. It's a crowded market - but there's a lot to play for.

Micron is also in the consumer SSD market. I told Micron's SSD marketers right at the outset of our talks that I wasn't interested in discussing that aspect of their business because isn't a consumer facing SSD site.

...Later:- in an interview with another PCIe SSD company (July 24, 2012) I was asked -

what do I think will happen to the PCIe SSD market?

Will it eventually be dominated by the semiconductor companies? like Micron and Intel - To find out what I said - the article
Micron mentions from SSD Market History

In April 2008 - Micron and Nanya Technology announced they were each investing $550 million in cash in a new joint venture.

In November 2008 - Micron demonstrated prototypes of fast PCIe flash SSDs with 800MB/s throughput, and hinted that 1GB/s SSDs could be available soon. The performance itself (for a prototype) is unremarkable - because 3 other oems already ship flash SSDs with similar (or faster) performance as commercial products. Z's Laws - Predicting Future Flash SSD Performance

In February 2009 - Micron announced restructuring plans will reduce employment at their Idaho sites by approximately 500 employees in the near term and as many as 2,000 positions by the end of the company's fiscal year.

InJuly 2009 - IDT announced it was working with Micron to develop a commercial PCIe flash SSD for the server market. Micron had previously tested market reaction by unveiling a prototype PCIe SSD (with 800MB/s R/W speeds) in November 2008.

In December 2009 - Micron announced it is sampling 6Gbps SATA MLC SSDs in 1.8" and 2.5" form factors. Micron's C300 SSD can achieve a read throughput speed of up to 355MB/s and a write throughput up to 215MB/s.

In February 2010 -Micron announced an agreement to acquire privately held Numonyx in an all-stock transaction worth approximately $1.3 billion.

In August 2010 - Micron Technology announced it is sampling the RealSSD P300 - a 200GB 2.5" SATA 3 SLC flash SSD with R/W IOPS of 44,000 and 16,000 respectively.

In June , 2011 - 30 months after pre-announcing its intentions to enter the PCIe SSD accelerator market - Micron today announced it is sampling the first products in a new family which will ship in the 3rd quarter of this year.

The company says its RealSSD P320h drive delivers upto 750K / 341K R/W IOPS, and 3GB/s / 2GB/s R/W throughput. It uses Micron's own 34nm SLC ONFI 2.1 NAND flash and has on-board RAM cache. Micron says it manufactures most of the chips used in the new cards a customized SSD controller.

In January 2012 - Micron announced it has acquired the assets UK based Virtensys which marketed rackmount SSDs stuffed with Micron's PCIe SSDs and supported by a patented multi-server sharing virtualization interface.

In January 2013 - Micron disclosed that in the past quarter SSDs had become 17% of Micron's nand business and the company estimates that 35% of the nand flash it supplies to trade customers end up in SSDs.
Micron samples its first real PCIe SSD
Editor:- June 2, 2011 - 30 months after pre-announcing its intentions to enter the PCIe SSD accelerator market - Micron today announced it is sampling the first products in a new family which will ship in the 3rd quarter of this year.

Editor's comments:- if it lives up to its promise - this new SSD range from Micron could be among the fastest PCIe SSDs around. From the viewpoint of a semiconductor memory maker - PCIe SSDs are attractive because they have high added value. That's the theory. In practise - to make an enterprise SSD business work you also have to invest a lot in continuing technical design, compatibility testing, customer support and marketing.
pcie  SSDs - click to read article The true test of Micron's new product therefore is not so much what it's like when it ships to users at the end of this year - but whether Micron decides to stay the course 2 to 3 years down the road.

Micron and Samsung launch new high density memory group
Editor:- October 7, 2011 - Samsung and Micron have launched a new industry initiative - the Hybrid Memory Cube Consortium - which will standardize a new module architecture for memory chips - enabling greater density, faster bandwidth and lower power.

"HMC is unlike anything currently on the radar," said Robert Feurle, Micron's VP for DRAM Marketing. "HMC brings a new level of capability to memory that provides exponential performance and efficiency gains that will redefine the future of memory."

Editor's comments:- HMC may enable SSD designers to pack 10x more RAM capacity into the same space with upto 15x the bandwidth, while using 1/3 the power due to its integrated power management plane.

The same technology will enable denser flash SSDs too - if flash is still around in 3 years' time and hasn't been sucked into the obsolete market slime pit by the lurking nv demons which have been shadowing flash for the past 10 years and been waiting for each "next generation" to stumble and be the last.
